Loss of power - need suggestions
About two months ago I was getting a cylinder 5 misfire so I replaced the spark plug and problem solved. I started to get another misfire about two weeks ago. Decided to replace all spark plugs and coils. When I got to my 4th cylinder it was covered in oil (I'm assuming the valve cover needs to be replaced). So I finish the install of coils and spark plugs. Misfire is gone however I notice loss of acceleration and I feel a lag with the power also ( its like I don't get the power until 4k rpm and then my car is finally like okay go and then the speedometer takes a second to catch up). I do not know much about cars so I'm reaching out to see if anybody can help me out with suggestions. No check engine light and its a 2004 coupe with 182k on it.

Yes, 6MT. I replaced the clutch about 20k ago and noticed the RPMs were a little different after but no real power loss. The clutch feels fine and I already went back over the coil packs. I didn’t reset the ECM though.
